Zayn's body art already includes a show of affection for his 19-year-old girlfriend, with the word "ZAP!", reportedly standing for Zayn and Perrie. He also has an image of a microphone on his forearm.

Louis’s collection of body art boasts an etching of the word "OOPS!" and a stickman on a skateboard.

But Harry Styles's grand total tops them, with an incredible estimated 30 tattoos. His etchings range from a 99p on his wrist, a "Hi" on his upper left arm and a black lock on his left wrist, as well as a butterfly on his chest.
